摘要
为了探讨影响夏季青年和牛超数排卵及胚胎移植生产因素,提高胚胎生产效果,对27头11~13月龄的青年和牛进行超数排卵生产胚胎,移植到124头荷斯坦奶牛和延边牛杂交后代母牛体内,结果表明:12月龄的青年和牛进行超数排卵可以获得满意的胚胎生产效果,体重300 kg以下,身高120 cm的个体在特定的剂量和供体选择下也可以达到较好的胚胎生产效果。健康的公牛所产的优质的精液是胚胎生产成功的重要因素。10 mL(200 mg)是青年和牛超排的适合剂量。在不考虑成本的条件下,埋置CIDR栓同期发情效果好,鲜胚移植受胎率53%,冻胚移植受胎率47%。
In order to explore the factors influencing superovulation and embryo transplantation of young Wagyu in summer,improve the embryo production effects,27 young Wagyu with the ages of 11 to 13 months were subjected to superovulation to produce embryos,and the embryos were then transplanted into 124 hybrid cows of Holstein cows and Yanbian cattle.The results showed that,the embryo production effect of 12-month-old Wagyu was good,and the Wagyu individuals whose weight was less than 300 kg and height was120 cm could also achieve good effect under specific doses and donor selection.The high quality semen produced by healthy bulls was an important factor for successful production of embryos.The optimal dosage of superovulation for young Wagyu was lOmL(200 mg).When the cost was not a consideration,synchronization of estrus with embedding CIDR had a good effect,the conception rate of fresh embryos was 53%,and that of frozen embryos was 47%.
